Feedback on 'Evolutions'

Computer technology is still on an exponential curve, as it has been for
the past 20 years. Somewhere I still have some of the trend lines. I recall
hard drives are going up 60% a year, CPU speeds double every 18 months to two
years, as does memory capacity. I don't see any limits (albeit with changed
technologies) for at least another 3 to 5 [computer] generations, which could
mean seven to ten years of continued increases in capabilities. One problem is
the cost of fabrication plants, now something over two billion US$ each (Intel
just opened [plant] #15 and should open #16 soon.)
